WebMar 23, 2024 · A concave down function is shaped like a hill or an upside-down U. It’s a function where the slope is decreasing. When it’s graphed, no line segment that joins 2 points on its graph ever goes above the curve. A concave up function, on the other hand, is shaped like a U. It’s a function where the slope is increasing. WebBut then concave up should equal convex down, i.e., the curve is the top (up) part of a concave region.
